I am always hoping that some body will get us out of the 50 years old dopamine box.

Scientists have established for the first time how specific "pathways" in the brain control our movements, opening the door for pioneering therapies to improve the motor skills of sufferers.

The discovery could also be used to develop treatments and drugs to improve the day-to-day lives of people with similar disorders including Huntington's disease and Tourette's syndrome, according to academics

Earlier this month scientists announced plans to restart research into a promising treatment for Parkinson's disease after overcoming a debilitating side effect that caused human tests to be abandoned nine years ago.

In the latest study by the Gladstone Institute of Neurological Disease (GIND) and Stanford University in the US, scientists used genetic techniques to make certain "pathways" – or circuits – in the brains of mice responsive to light.

The cells in these pathways could then be turned on and off by illuminating a laser shined through a hair-thin fibre optic cable inserted into the rodents.
